[0002] Prefabricated decoration is a type of building decoration method that uses factory-prefabricated building materials and components, which are assembled and installed on site to improve construction efficiency and quality and reduce construction time and resource waste. This method has received increasing attention and application in modern construction and decoration, especially in large-scale residential and commercial projects.

[0003] In the process of assembling interior decorative panels, clips are needed to quickly and accurately assemble prefabricated decorative panels on site. The design width of the existing clip slots is usually larger than the thickness of the decorative panels. Although such a design helps the panels to be smoothly inserted, excessive gaps may cause the panels to shake in the slots, affecting stability after installation. If the depth or height of the slots is not designed properly, the wall panels may not be fully embedded, affecting the installation effect. The design of some clips may make the installation and disassembly process more complicated, requiring specific tools or skills, increasing the difficulty and cost of construction, and the clips are fixed to the wall by bolts or glue, which may make disassembly difficult or damage the wall. Most of the existing clips are only suitable for decorative wall panels of specific types or sizes, and have poor versatility.

[0019] (2) The ends of the decorative plate are provided with horizontal snap-fit ​​pieces and vertical snap-fit ​​pieces. The horizontal snap-fit ​​pieces and the vertical snap-fit ​​pieces are pressed by the horizontal and longitudinal snap-fit ​​pieces to achieve a stable fixation of the ends of the decorative plate. The horizontal and vertical snap-fit ​​pieces can be applied to horizontal and vertical snap-fit ​​pieces of different thicknesses, thus solving the problem that the size of the slot of the traditional clip is slightly larger than the thickness of the plate, resulting in unstable fixation and easy shaking of the plate.

[0020] (3) The construction personnel can loosen the clamping screws to rotate the rotating disk relative to the supporting disk. The tilt angle of the plate block can be adjusted by rotating the rotating disk. The construction personnel can fix the rotating position of the rotating disk by re-tightening the clamping screws. This can be used for the connection and fixation of decorative plates of different shapes or tilt angles, and has strong applicability.

[0021] (4) The first fixing member and the second fixing member can clamp the support rod effectively, so as to achieve a stable fixation of the buckle unit on the support rod. The second fixing member and the first fixing member can be flexibly installed and disassembled without the need for additional construction tools, thereby improving the installation efficiency and reducing the burden on construction personnel;

[0022] (5) The upper and lower ends of the support rod are respectively provided with a top support sheet and a bottom support sheet. When fixing the support rod, the bottom support sheet can be placed on the indoor floor first, and the bottom rotating screw can be rotated by turning the bottom fixing knob. The bottom rotating screw moves upward under the limitation of the bottom support seat and drives the support rod to rise as a whole, so that the top support sheet contacts the indoor ceiling. Continuing to tighten the bottom fixing knob can increase the pressure of the top support sheet on the indoor ceiling. The support rod is firmly fixed by the upper and lower clamping action of the ceiling and the ground on the support rod. At the same time, the top support sheet and the bottom support sheet can be fixed to the ceiling and the ground respectively by bolts to increase the stability of the support rod;

[0023] (6) The upper wall of the top support sheet, the lower wall of the bottom support sheet, the end face of the horizontal pressure block, the upper wall of the longitudinal pressure block, the side wall where the rotating slot contacts the rotating disk, the inner wall of the first engaging slot and the inner wall of the second engaging slot are respectively provided with an anti-slip rubber layer. The anti-slip rubber layer can increase the friction between the surface contacts, thereby improving the fixing effect between the support rod, the buckle unit and the decorative plate.

[0047] like Figure 1-Figure 10 As shown, the upper wall of the top support plate 11, the lower wall of the bottom support plate 12, the end face of the transverse pressure block 233, the upper wall of the longitudinal pressure block 24, the side wall of the rotating slot 255 in contact with the rotating disk 23, the inner wall of the first engaging slot 252 and the inner wall of the second engaging slot 261 are respectively provided with an anti-slip rubber layer.

[0048] Working principle and workflow: The construction personnel first take out the support rod 1. The length of the support rod 1 can be prefabricated according to the interior design floor height, making it slightly smaller than the interior design floor height, which is convenient for the installation of the support rod 1. The number of support rods 1 is determined according to the overall area of ​​the decorative plate 3 to be installed. First, the support rod 1 is vertically placed on the ground, and the bottom support sheet 12 is in contact with the ground. The bottom rotating screw 14 can be rotated by turning the bottom fixing knob 13. The bottom support seat 122 is connected to the bottom rotating screw 14 through threads. The bottom rotating screw 14 gradually rises with the rotation, and the bottom limit rod 1221 The support rod 1 slides in the bottom limit block 15 to prevent the support rod 1 and the bottom support seat 122 from rotating as the bottom fixing knob 13 rotates. The support rod 1 rises as the bottom rotating screw 14 rises until the top support piece 11 contacts the indoor ceiling. The bottom fixing knob 13 is continued to be rotated to increase the pressure of the top support piece 11 and the bottom support piece 12 on the ceiling and the ground, so that the support rod 1 is firmly fixed between the ceiling and the ground. The fixing bolts can also be fixed in the bottom bolt holes 121 and the top bolt holes 111, so that the bottom support piece 12 and the top support piece 11 are firmly fixed to the ground and the ceiling through the fixing bolts.

[0049] After the support rod 1 is installed, the construction personnel will take out the clip unit 2 required to fix the decorative plate 3. The number of the clip unit 2 is determined according to the size and number of the decorative plate 3. Two clip unit units 2 form a group, and the upper and lower ends of the decorative plate 3 are respectively engaged and fixed. The construction personnel install a group of clip unit units 2 on the side wall of the support rod 1 according to the height of the decorative plate 3. The distance between a group of clip unit units 2 is slightly larger than the height of the decorative plate 3. When installing the clip unit units 2, the rotating fixing cover 27 can be loosened and removed from the limiting piece 253, the second fixing piece 26 can be taken out from between the limiting pieces 253, and the first fixing piece 25 can be placed on the side wall of the support rod 1 so that the side of the support rod 1 The wall is inserted into the first locking groove 252, and then the second fixing piece 26 is put back between the limiting pieces 253, so that the inner wall of the second locking groove 261 is fitted with the side wall of the support rod 1, and the rotating fixing cover 27 is screwed back to the side wall of the limiting piece 253. As the rotating fixing cover 27 is tightened, the holding block 271 will push the second fixing piece 26 to gradually press the support rod 1. Under the tight clamping action of the first fixing piece 25 and the second fixing piece 26, the buckle unit 2 is fixed as a whole to the side wall of the support rod 1. When the height position of the buckle unit 2 needs to be adjusted, the rotating fixing cover 27 can be loosened, and the connection between the second locking groove 261 and the side wall of the support rod 1 is loosened, thereby facilitating the movement of the height position of the buckle unit 2.

[0050] When fixing a group of fastener units 2, the plate slot 22 in the upper fastener unit 2 is set upward, and the plate slot 22 in the lower fastener unit 2 is set downward. After the position of a group of fastener units 2 is fixed, the horizontal snap-fitting piece 31 and the vertical snap-fitting piece 32 at the upper end of the decorative plate 3 can be snapped on the upper fastener unit 2, and the vertical snap-fitting piece 32 is inserted into the plate slot 22. At this time, the rotating fixing cover 27 in the lower fastener unit 2 is loosened to adjust its height position, and the end of the vertical snap-fitting piece 32 at the lower end of the decorative plate 3 is attached to the bottom wall of the plate slot 22 in the lower fastener unit 2, and then the rotating fixing cover 27 is re-tightened to fix the fastener unit 2. At this time, the height position of the vertical snap-fitting piece 32 snapped in the plate slot 22 on the upper and lower sides has been fixed, but the width of the plate slot 22 may be greater than the thickness of the vertical snap-fitting piece 32, which may cause the decorative plate 3 to be displaced in the horizontal direction, resulting in different groups of fasteners. The problem of uneven depth of the decorative plate 3 fixed by the single body 2 affects the overall effect after the decorative plate 3 is installed. Therefore, the horizontal pressing block 233 can be moved toward the side wall direction of the vertical locking piece 32 by screwing the pressing bolt 232, so that the side wall of the vertical locking piece 32 is tightly pressed against the side wall of the plate clamping block 21, thereby fixing the horizontal position of the decorative plate 3. At the same time, in order to further increase the fixing effect, the adjusting nut 212 can be rotated to make the adjusting screw 241 move up and down, and the adjusting slide bar 242 and the adjusting screw 241 slide in the pressing piece insertion hole 211, thereby driving the longitudinal pressing block 24 to press tightly against the side wall of the horizontal locking piece 31. Through the pressing action of the horizontal pressing block 233 and the longitudinal pressing block 24, the vertical locking piece 32 and the horizontal locking piece 31 can be firmly fixed in the plate clamping groove 22. By reasonably arranging the position of the fastener single body 2, the edges of the upper and lower decorative plates 3 can be tightly fitted. Figure 6 shown.

[0051] When the decorative plate 3 to be fixed is an irregular polygon or needs to be arranged at an angle, the fixing angle of the clip unit 2 can be adjusted, and the construction personnel can turn the clamping screw 256, and one end of the clamping screw 256 rotates to penetrate the side wall of the rotating slot 255 close to the first fixing member 25, and the side wall of the rotating slot 255 away from the first fixing member 25 is connected to the other end of the clamping screw 256 by a thread. Therefore, when the clamping screw 256 is rotated, the side wall of the rotating slot 255 away from the first fixing member 25 will be displaced forward and backward relative to the rotating disk 23. In the initial state, the side wall of the rotating slot 255 is tightly attached to the side wall of the rotating disk 23. At this time, the rotating slot 255 The groove 255 firmly clamps the rotating disk 23, and the rotating disk 23 cannot rotate. When the clamping screw 256 is rotated to make the side wall of the rotating groove 255 move away from the rotating disk 23, the rotating groove 255 no longer applies a clamping force to the rotating disk 23, so that the rotating disk 23 can rotate relative to the supporting disk 251. At this time, the plate clamping block 21, the plate clamping groove 22 and the rotating disk 23 are rotated to the angular position required to fix the decorative plate 3, and the clamping screw 256 is re-tightened to make the rotating groove 255 re-clamp the rotating disk 23 to fix the angular position of the rotating disk 23, and then the irregular polygonal or inclined decorative plate 3 is fixedly installed on the buckle unit 2, as shown in FIG. Fig.10 shown.

[0052] The present invention realizes flexible and stable installation and fixation of decorative panels 3 of different shapes and inclination angles through the flexibly adjustable snap-fit ​​unit 2, which can effectively prevent the decorative panels 3 from shaking and falling off, and ensure the stability and durability of the decoration effect. The design has strong versatility and can adapt to various decoration needs, and requires fewer construction tools. The installation process is simple and quick, which greatly reduces construction time and labor costs. At the same time, it has a low degree of damage to the wall, which conforms to the green and environmental protection concept of prefabricated decoration and helps to improve the overall quality and efficiency of decoration.

[0053] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.

[0054] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0055] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
